1. Preparation stage.
Adequate preparation is required before the empty container compression test can be carried out. First of all, it is necessary to choose a suitable test site to ensure that the test process will not be disturbed by external factors. Secondly, it is necessary to prepare test equipment, including empty box compression testing machine, pressure sensor, data collector, etc. In the process of equipment preparation, it is necessary to ensure that the accuracy and stability of the equipment meet the test requirements. Finally, it is necessary to prepare sufficient test samples to ensure the representativeness and reliability of the test results.
Second, the test phase.
When performing an empty container compression test, you need to follow these steps:
1.Place the empty box compression tester on a flat ground and make sure it is stable and motionless.
2.Place the pressure sensor on the lower platen of the testing machine and make sure it is in close contact with the lower plate.
3.Connect the data collector with the pressure sensor and set the acquisition parameters for real-time monitoring of the pressure data.
4.Place the test sample on the upper pressure plate of the empty box compression tester, and ensure that the flatness and compactness of the sample meet the requirements.
5.Start the empty container compression tester, apply pressure gradually, and monitor the change of pressure data in real time. In the process of applying pressure, it is necessary to maintain a constant speed and avoid sudden application or reduction of pressure.
6.Record changes in pressure data and observe the deformation of the sample. When the sample is cracked or deformed, the compressive strength and pressure value at this time are recorded.
7.Multiple tests are performed and averaged as the final test results. During the test, the same test conditions and parameter settings are maintained to ensure the accuracy and comparability of the test results.
3. Result processing stage.
After the empty container compression test is completed, the test results need to be processed and analyzed. First, the test data needs to be collated, including the compressive strength and pressure values of the individual samples. Then, the data needs to be counted and analyzed, and statistical indicators such as mean and standard deviation need to be calculated. By comparing the test results of different samples, it is possible to evaluate the advantages and disadvantages of their compressive performance. Finally, it is necessary to analyze and summarize the test results accordingly to provide valuable reference for subsequent research and application.
4. Precautions.
When performing the empty container compression test, the following points need to be noted:
1.Ensure the stability and accuracy of the test site and equipment, and avoid the influence of external factors on the test results.
2.In the process of applying pressure, it is necessary to maintain a constant speed and avoid sudden application or reduction of pressure. At the same time, it is necessary to pay close attention to the deformation of the sample to prevent the sample from breaking or being damaged.
3.When performing multiple tests, the same test conditions and parameter settings are maintained to ensure the accuracy and comparability of test results. At the same time, the test data should be statistically analyzed to evaluate the compressive performance of the sample.
4.When processing the test results, it is necessary to carefully organize and analyze the data, and analyze and summarize accordingly according to the actual situation. At the same time, the test results should be compared with other studies or standards to evaluate their merits and application value.
